Yeah, we get to see him and her connecting in a lot of ways and their relationship developing and then these fractures kind of seeping in and them both being torn in different directions. But with such a kind of closeness that they’ve already had, it makes it very difficult. And those scenes were really hard but hopefully we’ve captured something that's really good. 

As we’ve already seen, the relationship is becoming less the son and mother and more the king and his subject. It’s not quite as drastic as Joffrey, but it’s there.
Yeah, no as bad as that. But, yeah, that's where the relationship is going. And it seems like it’s never had to be that because Robb and Catelyn, they’re always on the same page, I think.

Now in Season 2 they’re not. Catelyn’s main desire is still to reunite her family and she cares about her daughters and her sons. And for Robb now, as much as he wants to get this revenge and get his family back, that's only a tiny part [of his worries]. He’s now got 20,000 men, their families, their children, their wives, their mothers and fathers who are as important to him as his own family and he can't hold them in a higher regard.

I think Catelyn struggles to deal with that because the whole reason we started this war was for our family and now for Robb he knows that the picture is much bigger. There are many families involved now and he’s got to be the leader of that army and not just be driving things with his own desire. And I think he struggles to keep up with that and to engage with that. 

Right. I saw a fan page with the header, “Robb Stark, the people's hero.” 
[Laughs.] Well, that's good. I quite like that. I like that. I think he is one of the most honest characters in the show, right? He’s one of the most genuine people and he’s one of the only characters that I don't think is really driven completely by revenge. I think that's maybe what sparked things, but he’s driven by wanting Westeros to be a better place and I think that's kind of the rare things. Every other character is driven by money or greed or lust and desire, and I think Robb is genuinely, like his father, driven to make this place the best it possible can be. So I wouldn't argue with that title. I would agree with it. 

I think he’s a lot like his father. And I was going to ask do you think that, because he is so much like his father, do you think he’ll eventually make the same mistake that his father made, which is to keep his honor above all else? 
I don't know. I think his honesty, his desire to follow his heart and to do the right thing is much like his father. But what we’re going to see in this season is him slowly getting worn down and you see differences between him and his father. The strength of his father was sometimes misused and misjudged. I think with many of the characters in this show, the good guys—the guys with good hearts and with the good in the mind—aren't necessarily the survivors of the show because they’re not manipulative enough and they’re not willing to sacrifice or to do wrong in order to do right. And I think that maybe could be one of Robb’s downfalls. 

Right. Well, this weekend’s episode another one of Robb’s attacks, and we see the aftermath of that. Roose Bolton wants to torture survivors, but Robb is shocked at the thought of it. I love the scene.
Yeah. No, Robb can't engage with that. And hopefully, if I’ve done that scene right, you should see a kind of glimmer with Robb of him being slightly overwhelmed by this. I mean, he’s done these battles. He’s seen it. But I don't think it’s getting easier for him to see this much death constantly and that's why he can't face that.

He is a leader and he’s got the respect of his men and he’s trying his best, but there's part of him that's so human, he can't be a tyrant because that doesn't make him any different to Joffrey, then. 

So then the other thing we see is the introduction of Oona Chaplin.
Yeah, the first woman in his life—[laughs]—in that way, yeah. And it’s different for Robb. I think Robb’s full first times this season. It’s the first time he’s really leading an army and has the respect of his men, it’s the first time he is having these huge disagreements with his mother and it’s the first time that he’s met a woman that's turned his head and Talisa really does that, not that he realizes it to start with. … And Oona is just fantastic. 

What I love about their relationship is they connect in a way that Robb’s not even aware of, I think. I think it takes its own life and it goes on its own journey without it being manipulated from either party. That's what kind of makes it so good, I think, is that it comes from a kind of passionate, honest place

When I talked to Kit, he talked about how Jon has never really been with a woman, so the woman thing becomes problematic for him. Is that going to be the same way with Robb, do you think? Or was he a player back in Winterfell. 
[Laughs.] No, that’s one of the things that George didn't tell me. It’s a given Theon was playing around for a while, I think. But with a character like Robb, we don't know. We’re not told that much. I interpreted that he’d not been with a woman before. He’s not been and when he meets Talisa, I think it’s a first time for lots of things. 

Tell me about the costumes.
You know, it’s one of those funny things. When I got cast we started having these costume fittings and I’m like, “This is awesome. Look at this costume. It’s brilliant.”

Then we started doing the show and it’s really awesome and then it’s kind of like 5 a.m. on the twentieth morning of shooting and your back is killing you and you're like, “I hate these costumes!” In King’s Landing in a T-shirt, right?
